Fire TV Software update 5.2.1.1 (551203220) begins rolling out

A new Amazon Fire TV software update, carrying version number 5.2.1.1 (551203220), has just started rolling out to devices. Currently, I only have confirmation that the Fire TV 1 is receiving this update. Amazon has updated their source code notice page to include this new software version. It is listed under both the Fire TV 1 and Fire TV 2 sections, so it appears the Fire TV 2 will also be receiving this update. The Fire TV Stick section of the page has not been updated, which is a bit odd since the last 3 software updates have arrived on all devices simultaneously, so the Stick might be excluded from this update.

I have received the update on a Fire TV 1 and will begin digging through to see what changes, if any, this update brings. Judging by the small size of the update, and the small number increase from 5.2.1.0 to 5.2.1.1, I would guess this is a bug fix update that doesn’t bring any new features.

Software update 5.2.1.1 on the Fire TV 1 still has the QuadRooter vulnerability. I have run the scanning utility and all 4 vulnerabilities remain present with this new software version.

Remember, Fire TV software updates roll out slowly and it usually takes up to 2 weeks for all devices to receive a new software update, so don’t be alarmed if your device has not received this update yet. You can go into your Settings > System > About menu to force an update check, but if it’s not your device’s turn to update, there is no way to force the update or manually install it. Be sure to comment below when you receive this update and on which device. Also, please let me know if you notice any changes, new features, or bug fixes.

Hello Elias, do you know if this update is still being sent from the same Amazon sources as previous updates? Meaning, if I have been successfully “update blocked” from the past couple updates will I continue to be? Thanks! It’s these little updates that worry me the most…

Amazon Fire TV 2ngGen just took the update. Message saying “this may take up to 10 minutes to install…” and it did. It took about 10 minutes to install. No noticeable changes, at least to the lay user.

I hope this fixes the pausing issues, my pausing issue, happens on youtube and sometimes kodi. Even when streaming from my NAS :(. I’ve tried 5G and 2.4G wifi on my Fire TV Stick. Got full signal as well :S

What do you mean stuck on 51.1.6.3_user_516012020? Do you just have software updates blocked oe are you rooted with software updates blocked? IF just on 51.1.6.3_user_516012020 with software updates blocked…just unblock and you’ll update to the latest version. If rooted on with 51.1.6.3_user_516012020 then follow the guide to istall TWRP and rbox’s pre rooted rom of the software version you want.

Elias Could you, or anyone that has received this NEW Fire TV Software update 5.2.1.1 (551203220), please confirm to all of us, if KODI and SPMC are still working flawlessly after updating the FireTV1 and FireTV2 Boxes ?

Kodi installs fine on the Fire TV 1 with 5.2.1.1. That’s the only box I have that received the update so far, and it’s not my main Kodi box, so I can’t say if anything in Kodi is broken, but I doubt it.

So far I’ve only noticed the two things I’ve already posted about: The ad tracking option, and the PIN prompt for app launches. Once I capture the update package I’ll be able to dissect it and learn more.

Elias,
Hello i have a Fire TV Stick (1st Generation) no voice remote type, i disable the FS from doing any update since the 5.2.1.1 update was messing with Kodi and debloater, it is not safe to let it go ahead and do the update so i have the latest OS, thanks.
